The Ossario di San Martino is a small chapel that houses over 1,200 skulls and over 2,000 bones that belonged to fallen soldiers who fought in a key 19th-century European conflict.
In 1859, during the Second Italian War of Independence, there was a great battle here, more commonly called the Battle of Solferino. It was fought out between Austrian and the Piedmontese army. Solferino was the largest battle since that at Leipzig in 1813. As a result of their defeat, the Austrians lost their grip on the region.
Originally built as a chapel, the Ossario di San Martino was later converted into an ossuary, which was opened in 1870. Thousands of bones and skulls from soldiers from both sides, exhumed from the mass graves in which they were buried, rest in a display behind the altar. The exterior walls contain plaques commemorating the fighters from different cities and regions who took part in the war.
House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
